Dear all !

   I wanna put the multi-layer gasket elements  in my CAE model. The brief model is shown as below.

  The model is one combination that including two blocks, gasket elements, thin plates. There are two different gasket elements, the gaskets with initial gap and without initial gap. All gasket elements have been set as thickness-direction behavior only.

  For the interactions between gaskets and thin plate, I refered to the setting described in the help doucment. The contact-tied  surface behaviour was chosen at the bottom side of gasket, it was the general surface based contact in the other side.

I applied the vertical displacement on the upper block to press the model. The Ux&y of thin plates and the uppper block were fixed to prevent from the rigid motion of gasket.

  But actually the rigid motion of the gaskets with initial gap at x direction was observed in the early stage of the compression. The model appeared to diverge.

   Anybody can share some suggestions for this case ?

Thanks.
